6.17 Heating curve
The heating curve is used to generate the fl ow temperature setpoint, which is used to
maintain a certain fl ow temperature depending on the prevailing weather conditions.
The heating curve can be adjusted with a number of settings, thus matching heat out-
put and room temperature to individual needs.
As the heating curve slope is raised, the fl ow temperature increases the quicker the
lower the outside temperature or, in other words, if the room temperature is not cor-
rect at low outside temperatures but correct at higher outside temperatures, the heating
curve slope requires readjustment.
Increase adjustment: Raises the fl ow temperature, especially when outside temperatures
are low.
Decrease adjustment: Lowers the fl ow temperature, especially when outside temperatu-
res are low.
Default setting 1,5
Parallel displacement of the heating curve is used to change the fl ow temperature evenly
across the entire outside temperature range or, in other words, if the room temperature
is always too high or too low, a readjustment must be made with the help of the parallel
displacement.
